#Random Hex colour

Want a random colour between white and black?

"#" + (Math.random() * 0xffffff | 0).toString(16)

That is all.

[Update: after I posted this I thought... i bet this has been done a zillion times already. It was, and by Paul Irish in 2009 no less. Additionally - it doesn't work. The best looking one there was:

'#'+('00000'+(Math.random()*(1<<24)|0).toString(16)).slice(-6);
